,Letters Patent No. 87,044, dated Februar/ry 16, 1869.

IMPROVE!) FRICTION-CALENIIDER FOR PAPER AND OTHER FABRICS.

The Schedule referred to in'these Letters Patent and making part ofthe im.

.l'o lall whom it may concern Be it known that we, WILLIAM W.-HA1D1N.G and WILLIAM H. Sonny, of Philadelphia, Pennsylvania,

'have invented a new and useful Improvement in Friction-Calenders for Paper and other Material; and we do hereby declare the following to be a full and exact description of the same, reference being had to the annexed drawing, forming a part hereof', which represents a perspective view of our improvement.

Our invention consists in attaching to the outer ends of the bottom and top rolls, two friction-wheels, to Agive an unbroken, uniform rubbing or friction to the paper or material. v

Hitherto it has been endeavored to accomplish this Yresult by the use of cogs or gear-wheels, but the action O represents ak large driving-roll, made of iron, say eighteen inches in diameter.

D is an intermedi' te roll, made of iron or compressed paper, and

E isA a compressed-paper roll'.

F is a friction-roll, made of iron or steel, and driven by friction-pulleys B B', at each end, which are in contact, and which, in their turn, are driven by frictionwheels A A', the power being applied -by a belt and pulley, at G, in the usual way. The advantage of this arrangement is, that aumform, continuous motion is given t'o the upper roll at all times.

Having thus described our invention,

What we claim, and desire to secure by Letters Patent, isp The combination of the calender-rolls C, D, E, and F, and .the contact friction-driving pulleys A B, or A' B', for dri ving the upper roll.
